Great article! The days of a logo design NEEDING to work in black & white are long-gone. That being said, a great logo design WILL work in black & white—perhaps with a little modification. So if your logo doesn’t work in black and white, perhaps you should re-think it.
While the linked article goes against my advice on creating a logo you can live with and still get paid, I still stand behind what I wrote back in 2008.
